ARTIMUS W. SHIDLER, OF FARMINGTON, NEW MEXICO.

STEAM-GENERATOR.

rea ers.

To all whom it may concern Be it known that I, ARTIMUs W. SHIDLER,

a citizen of the United States, residing at Farmington, in the county of San Juan and State of New Mexico, have invented certain new and useful Improvements in Steam- Generators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as Willenable others skilled in the art to which it appertains to make and use the same.

This invention relates to a device which is.

particularly designed for removing snow from railroads, streets, street car tracks or the like and the primary object of the invention is to provide a snow removing device as specified which utilizes steam for melting the snow which materially decreases the cost of removing snow from city streets, railroad tracks or the like in that the cost of hauling the snow is eliminated.

A further object of this invention is to provide a device as specified which is mounted upon an ordinary fiat car and includes a boiler structure having a plurality of pipes, through which water passes, for conversion into steam and to mount-fire boxes within the boiler structure for converting the water into steam during its passage through the pipes.

A further object is to provide aflexible hose which is .connected to the steam chest of the device and has a nozzle on its outer end for directing the steam from thesteam chest against the snow for the purpose of melting the latter.

A further object of this invention is to provide a pump structure for forcing water into the boiler tubes and also to provide a blower structure for increasing the action of the fire within the fire boxes.

With the foregoing and other objectsin view this invention consists in such novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and claimed.

In describing the invention in detail reference will be had to the accompanying drawings wherein like characters designate like and corresponding parts throughout the several views, and in which:-

Figure 1 is a side elevation of the improved snow removing device.

Fig. 2 is a top plan view of this snow re moving device.

7 Specification of Letters Patent.

Patented Oct. 1, 1918.

Application filed May 6, 1916. Serial No. 95,953.

Fig. 3 is an end view of the snow remov-.

ing device.

Fig. 4 is a cross section through the device, and

Fig. 5 is a detail view of the nozzle.

Referring more particularly to the drawings, 1 designates a portable flat car of any ordinary construction upon which the improved snow melting device is mounted. The snow melting device which is generically indicated by the numeral 2, includes a casing having an open bottom, which is built up of pipes extending longitudinally of the casing and having their ends connected by the ordinary type of U-coupling's indicated at 3.

The pipes 4: which form the upper portion of the casing 2 extend across the ends of the casing as clearly shown in Fig. 3 of the drawings so that they form the entire upper portion of the casing. The ends of the lower portion of the casing are formed by sheet metal plates 5 which are provided .with doors 6 to permit of the throwing of fuel, such as coal or the like interiorly of the casing. The bottom of the casing is formed of pipes 7 which form grate bars and also water or liquid containers. A pump structure 8 of any ordinary construction is operatively connected through the medium ofa short length of pipe 9 to the series of pipes of which the casing is formed,

for forcmg water into the series or system of pipes. A water feed pipe 10 communicates with the pump 8. The casing has a steam chest 11 carried thereby, at the top of the easing into which the steam passes from the series or system of pipes. It is preferable to have a lining indicated at 12 positioned within the casing 2 for preventing the action of the fire therein from being applied directly to the pipe. A safety or pop-off valve structure13 is carried by the steam chest 11. A water gage 14 is connected in the series of pipes for indicating the quantity of water therein.

A blower 15 is provided, the outlet 16 of which communicates with a pipe 17. The pipe 17 extends longitudinally along one side of the casing 2 and has communication with transversely extending outlet pipes 17 which guides the air blast from the fan or blower 15 upwardly into the fire boxes, for increasing the combustion of the fuel therein. A fire box is positioned at each end of the casing.

An outlet pipe 20 is carried by the for-- ward end of the steam chest 11 and it has a valve structure 21 carried thereby for controlling the passage of steam out of the chest and through the flexible hose 22 which is connected to the pipe 20. A nozzle 23 is mounted upon the outlet end of the flexible hose22 and it is preferably rovided with an elongated slot 24: out of whichthe steam egresses, for causing the steam to engage the snow in a fiatrelatively broad stream. Coal or fuel retaining hoppers or boxes 24E are carried by the car 1 and are positioned so that the fuel may be conveniently thrown therefrom into the fire boxes.

A smoke stack 25 of any suitable construction is provided for permitting of the escape of the products of combustion from the fire boxes.

In the operation of the improved device for melting snow from railways, streets or y the like, water is fed to the series or system of pipes by the action of the pump 8 and the fire built within the fire boxes at each end of the casing'will convert the water into steam which steam will 7 pass upwardly through the series of pipes into the steam chest 11'. The outlet of the steam from the steam chest 11 is ontrolled by the operation of the valve and when it is desired to melt the snow,the valve is opened which permits the steam to pass outwardly through the boss 22 and the nozzle 23. The nozzle 23 is manually operated or moved about so as to guide the issuing steam on the snow forthe purpose of melting the latter and causing it torun ofl the track or street in liquid form thereby eliminating the inconvenience of loading and hauling the snow.

From the foregoing description taken in connection with the accompanying drawings,

Copies of this patent may be obtained for the advantages of construction and of the method of operation of the improved device formelting snow from railroads, streets, etc., will be readily apparent to those skilled in the art to which this invention appertains, and while in the foregoing description, the principle of the operation of this invention has been described together with various features of construction, it is to be understood that certain minor features of construction, combination" and? arrangement of parts may bealteredtosuit practical: conditions-provided such alterations are compreliended within the scope of what is claimed.

What is claimed is:--

A device of the character set forth comprising; a casing having an open bottom and ends, said casing having its top wall domeshaped and provided with a longitudinally extendingtgroove, a plurality of horizontally disposed pipes placed onthe casing, series of pipes closing the upper half of the ends of said casing and connected in series with some of the horizontal pipes, a series of bottom pipes closing the bottom of said casing to form a grate and connected in series with each. other and to some of the horizontal pipes, plates closing the lower half of the ends of said casing and having fuel receiving openings topermit a fire to be builton the bottom pipesfrom each end of. the casing, and a: steam dome located in the groove and; connectedto the series of horizontal pipes for.

receiving ster m from the pipes.

In testimony whereof I affix my signature in presence of two witnesses.
